Foam

Q. How many bottles are in each foam test kit?

A. We offer a 4-bottle kit as well as a 2-bottle kit. Please order the kit that best suits your needs to save on shipping costs.

Q. Why would the foam fail?

A. There are various reasons why foam may fail. See the article Why Fire-Fighting Foam Fails for details or call 1-800-632-2304 to speak to one of our chemists.

Q. How do I take a sample?

A. Proper sampling of foam is very important, see the article Tips on Proper Sampling for more information. We also have a video on how to prepare your samples to send to us for testing.

Q. What is the Mineral Oil test?

A. Mineral oil is sometimes added to the top of alcohol-resistant aqueous film forming foam (AR-AFFF) by the manufacturer to prevent evaporation of the solvent in the foam concentrate. Read more by going to the Mineral Oil Determination Test article published in October 2014.

Q. What is Proportioning Testing?

A. Verifying that a firefighting foam system accurately proportions foam and water is critical to the system’s effectiveness in the event of a fire. Our Proportioning Testing article explains why you should consider proportioning testing.  A proportioning sample requires a sample of concentrate, a proportioned sample, and a sample of system water.

Q. How often are we required to test our foam?

 A. NFPA 11 2016 Edition Section 12.6. states At least annually an inspection shall be made of foam concentrates and their tanks or storage for evidence of excessive sludging or deterioration. Samples of concentrates shall be sent to the manufacturer or qualified laboratory for quality condition testing. For more NFPA information, visit nfpa.org.

Q. How much sample (ml or ounces) is required for testing?

A. We require at least 8 ounces or 250 ml. For IMO testing, a 2-liter sample should be taken.

Q. Should I also test the bladder water?

A. The National Fire Protection Association Standard 25, Inspection, Testing and Maintenance of Water-Based Fire Protection Systems recommends foam bladder tanks systems be inspected at least annually.  Click on the following link to read more about Bladder Water Testing.

Q. Should I take a top and a bottom sample?

A. If the sample being taken is a foam concentrate sample, keep in mind that these tanks contain a large volume of foam that may not be uniform throughout. The tank should be sampled from two different areas, the top and the bottom for example, to help ensure that the foam is acceptable throughout. Click on the following link to read Tips on Proper Sampling.

Q. What type of tests are performed on a standard foam concentrate?

A. Go to the Foam Testing Explanation article for information on performance and physical tests performed on foam at Dyne.

Q. What is the best way to package and return the full sample bottles in the kit box?

A. View the video: Preparing Your Foam Samples for Dyne. Please fill the sample bottles to the fill line. Be sure to tighten the caps securely as they can loosen in transit. Tape the caps shut (electrical tape works great). Place the full bottles in the plastic bag and seal the bag. Make sure to include the return form outside of the plastic bag and remember to include a PO or credit card (do not send a check). If you tape the outside of the box shut, that helps too.

Remember to return the kits using the enclosed UPS return label or via the U.S. postal service. If you use the UPS label, be sure to keep the tracking number in order to be able to follow the package to Dyne. UPS Ground generally takes 3-5 days within the U.S.

Q. What do I do if my foam sample fails? Can I talk to someone at Dyne?

A. Call Dyne at 800-632-2304 to discuss your test results with a chemist. We also have a video and published an article on Why Fire-Fighting Foam Fails in June 2015.

Q. I have some bottles, what can I fill out and return with my samples?

A. Click here to download the foam sample return form.

Q. Who can I contact for maintenance on the tank or new foam?

A. View our list of foam manufacturers.

Q. What temperature range should the foam be stored?

A. For the purposes of test uniformity, a liquid concentrate is to be categorized according to the minimum storage temperature at which it may be inducted or proportioned in acceptable concentrations. Minimum storage temperatures are to be minus 20°F (minus 28.9°C), 0°F (minus 17.8°C), 20°F (minus 6.7°C), or 35°F (1.7°C).

UL Statement: Liquid concentrates may be stored in the original shipping containers or in pressure-proportioning tanks. Liquid concentrates are not intended to be stored at temperatures lower than those for which they have been certified or above 120°F. They should be stored in locations free of excessive moisture to avoid external corrosion of containers and other equipment. For more specific information, reference the foam manufacturer.

Q. I see International Maritime Organization MSC (IMO) on the return form. What is IMO testing?

A. Filling out the paperwork for a sample of firefighting foam to send into Dyne for testing can be confusing if you are unfamiliar with some of the language or testing methods used in the firefighting foam business. IMO and NFPA have similar standards for firefighting foam testing except IMO stipulates a slightly more rigorous analysis. Factors to consider when making this decision are detailed in the article NFPA or IMO Foam Testing – Which is Right for You.

Sprinkler Head Testing

Q. How many sprinklers must be removed from a system for testing?

A. NFPA 25 2017 Edition states "A representative sample of sprinklers for testing per 5.3.1.1.1 shall consist of a minimum of not less than four sprinklers or 1 percent of the number of sprinklers per individual sprinkler sample, whichever is greater.

Q. Have sprinkler heads ever been recalled?

A. The largest recall occurred back in 2001 and it involved a large number of heads utilizing o-ring seals. Many of the manufacturers of these recalled heads offered a free replacement but only for a specific time period which has since expired. If a recalled head is sent to Dyne for testing, the head will be put through the testing process and will receive a response time result.

Q. Can sprinkler heads that have been painted be tested?

A. NFPA 25 allows only factory painted sprinkler heads so any heads that have been field painted must be replaced.

Q. Do dry heads need to be tested?

A. Yes dry heads are also required to be tested. In fact, dry heads have been shown to be more likely to fail sooner in the field and as a result, they must be either replaced or tested every 10 years. 

Q. What if my sprinkler heads do not fit in the Dyne sprinkler kit box?

A. The Dyne sprinkler kit testing box is designed to accommodate only standard sized sprinkler heads. Some heads, including dry sprinkler heads, will not fit in our standard kit. For larger heads, customers will have to purchase appropriate shipping and packaging material.

Antifreeze

Q. I have a foam testing kit, can I use the same bottles for antifreeze testing?

A. Yes, Dyne sample bottles are used for both foam and antifreeze testing.  The paperwork can also be used for both kinds of testing, there are check boxes for antifreeze solution on the form.

Q. Should I test my Antifreeze before winter?

A. Yes, If a premix antifreeze solution is being used, it must be tested annually, before the onset of freezing weather. Read the article Antifreeze Testing Before Winter for more information.
